>General Running>Training for Uphill Mountain Race
Unless you live near a big mountain, it's probably hard to find a 10 mile hill. I have used a treadmill to train at a challenging incline and speed for extended times - 1 hour, 1.5 hours. (but slow enough so I could keep a fairly steady pace through the run.) That gets me somewhat used to running up hill for that amount of time. Also - intervals using 5 - 8 % incline on the treadmill, which is good for strength and maintaining some speed. But it's good to find some real hills, too - 0.5 mile to 2 mile hills to run up and down, if possible.
